F1 Ln Nov. 26 920. 4 SHEETS-SHEET 2 CRlMP-ING MAc'HrN Fl LED Nov. 26 4 SHEETS-SHEET 4 The rolls 1 and 2 are journaled in bearings on the side members B, and means is provided for causing said rolls to rotate continuously when the machine is in operation, the means herein illustrated for this purpose consisting of a drive shaft 3 provided with a pinion 4 (shown in broken lines in Figure 1) that meshes with a gear 5 secured to one end of the bottom roll 2. One of the plaiting rolls is heated, preferably by an electrically-operated heating element D, so as to cause the strip to be heated during the op-l eration of plaiting the strip.- The heating elementofthe machine herein illustrated is arranged inside of the bottom roll 2 and consists of a resistance wire 6 wrapped around a -core 7 connected to aplug 8 which is screwed into one end of the roll 2, as shown in ldigure 7. Electriccurrent is supplied to the heating element :DbybrushesQ connected to an electric.supply circuitl 10 yand arranged so that they will bear upon a conducting ring` 11.. to whichthe resistance vwire 6 is connected. It will,lof course, be understood that any other suitable means could be 'used for heating. either one or both of the plaiting rolls Without departing from the spirit of my invention.

AThe means that I prefer to use for feeding the strips of paper or other sheet material that are to be pla-ited, into position to be acted upon by the plaiting rolls consists of a plurality. of endless sprocketA chains 12 that travel over sprocket wheels 13 on two herizontally-disposed shafts 14 which are mounted in the side members B of the frame ofthe machine, the table C being slotted so as to receive said chains and each of said chains being provided with a plurality ofA projections 15, as shown in Figure 4, that are adapted to engage a strip :i0 lying on the table C, as shown in lligure 5, and feed said strip rearwardly into position to be engaged by the rolls 1 and 2. rlfhe sprocket chains of the strip feeding mechanism move continuously when the machine is in operation and are driven by a gear 16 on one of the sprocket wheel shafts 14 that meshes with an idler arranged under the gear 16 and secured toan idler 17, which, in turn, meshes with a gear 1S on the left hand end of the plaiting roll 2, as shown in Figure 2. A feeding mechanism of the construction above described is desirable, in that it ena-bles the machine to be run at a much higher speed than is possible with a reciprocatingfeeding mechanism and it gives the operator more latitude in arranging the strips on the feed table, due, of course, to the fact that the constantly moving chains are provided with a plurality of sets of feeding projections 15. rlhe teeth of the rolls 1 and 2 mesh with each other so that the rotary movement of said rolls will cause the strips to be fed rearwardly between said rolls, and in order that the plaited strips will not stick to the heated roll 2, l have combined a stripping mechanism with the bottom roll 2, said stripping mechanism consisting` of pieces of wire or small rods 15a arrangedin annular grooves v`in the roll 2, as shown in Figure 8 and connected at their front and rear ends, respectively, to the table C and to the stationary guideway member of the compressing mechamsm.

rcompressing mechanism is arranged at the rear of the plaiting rolls for exerting pressure on the plaited strips in a direction to press the plaits of same tightly together. Said compressing' mechanism comprises a movable member, preferably an oscillating member lll, arranged at the rear of the plaiting rolls, as shown in Figures 4, 6 and 8, and provided with a. projection 19 that cooperates Awith a jaw 20 to compress the plaited strips m edgewise. "The projection 19 is' formed by a transversely-disposed bar that is set in a channel or groove in the convened face of the member E. Said'projection is capable of moving relatively to the member E, and it is backed up by coiled expansion springs 19L1 that normally hold it projected, as shown in Figure 6. The oscillating member E is of substantially segmental form and is of approxiu'xately the same length as the plaiting rolls. Said member is carried by arms 21 on an oscillating shaft that is jourualed in the side members B of the frame of the machine, said shaft being rocked intermittently when the machine is in operation, preferably by a link 23 which is pivoted at its upper end to an arm 24 on the end of said shaft and piroted at its lower end to a gear 25 which meshes with the gear 18 on the left hand end of the plaiting roll 2, shown in Figure 2. if desired, the4 arm 24 can be adjustably connected to the shaft 22, so as to enable the stroke of the member E to be changed so as to vary the pressure which the )arts 19 and 20 exert on the strip. Unetype of 'adjusting means that can be used for lthis purpose consists of a set screw 24a for clamping the arm 24 to the rock shaft 22 and adjustable stop screws 24b in said arm arranged on opposite sides of a rib on said shaft, as shown in Figure 2%. The projection li) ou the oscillating member E and the jaw 2f.) with which said projection cooperates both extend transversely of the machin and are of approximately the same length as the plaiting` rolls. `The aw 2O is preferablv mounted in such a manner that iturilli-.nove slightly 'a the direction in which the projection 12 moves during the compre ing operation, so to inc-reas*l 'the time that the cempressed strip is clamped between lthe projection 19 and jaw 20. ln the machine herein shown the lower end of the jaw 20 is hinged or pivotally connected at 26 to de pending` arms 27 on a stationary guideway member 28 which extends transversely of the machine at the rear of the plaiting roll 2 and the top surface of said guideway member 25 is slightly concaved so that it will conform approximately to the conveXed surface of the oscillating member E, and thus serve as a supporting surface for the plaited strip fr when said plaited strip is being moved into engagement with the jaw 2O at the lower end of the guideway member 28.

The oscillating member E is provided with ,teeding devices 29 arranged so that they will engage a plaited strip that projects rearwardly from the plaiting rolls, as shown in Figure 6, move said plaited strip downwardly over the guideway member 28 into engagement with the jaw 20 and then clear or pass over the upper end of said jaw 2O during the last portion of the downward stroke of the member E. In the form of my invention herein illustrated the feeding devices 29 are slidingly mounted in slots in the oscillating member E and are connected to a transversely-disposed bar 30 which 1s carried by pivotally mounted rock arms 8l on the member E, said bar 30 being acted upon by springs 32, shown in Figures 6 and 8, that normally exert pressure on said bar in a direction tending to hold the feeding devices 29 projected, or7 in other words, in such a position that they exten-d beyond the convened surface of the member E. During the downward stroke of the member E the free ends, 31 of the rock arms 3l engage cam plates 33 on the side members of the iframe of the machine which are so disposed that the bar 30 will be moved suiiicientlyl to retract the feeding devices 29 or render them inoperative after said feeding devices have moved the plaited strip into engagement with the j aw 20, said cam plates 33 being so designed that said feeding devices will be held in their retracted position until they clear the upper end of the jaw 20 on the forward o-r upward stroke of the member E.

As previously stated, the jaw 2O is so constructed that it will yield slightly during J[he compression stroke of the member E. Preferably, means is provided tor varying the time at which the jaw 20 starts to move rearwardly and Yfor varying the degree ot movement of said jaw. 1n the form ot my invention herein illustrated the jaw 2() is combined with guide rods 3d (see Figure 8) that project rearwardly from the stationary guideway member 28. vThe guide rods Sil pass loosely through the member 28 and the rear ends of said rodsare screwed into holes in the jaw 20, lock nuts being` mounted on the ends of said guide rods at the rear of the jaw 20, so as to prevent said rods from turning relatively to said jaw. Coiled expansion springs 35 which are arranged in pockets in the guideway member 2S between the bottoms oif said pockets and heads 3ft on the guide rods 34: normally exert pressure on the Jaw 20 in a direction to force said jaw ttorwardly or towards the guideway member 28. During the compressing operation the springs 35 yield sufficiently to permit the jaw 20 to move rearwardly into the position shown in Figure 8. At this point in the cycle of operations of the machine, namely., after the springs 35 have been compressed7 the jaw 20 is engaged and locked in its rearward position by a locking means which will be hereinafter described. rl`he rearward movement oi the jaw 2O is limited by adjustable stops 20a on the member 28 that pass freely through the jaw 20, (see Figures 9 and l0). It it is desired to vary' the time that the jaw 2O starts to move rearwardly with the projection 19 on the member during the compression stroke oi"- said member, thus varying the degree o compression on the plaited strip.7 the guide rods 3d can be Screwed into or out of the jaw 20, so as to vary the tension of the springs 35. By screwing said guide rods further into the jaw 20 the tension o'i the springs 35 will be increased7 and accordingly, the jaw 20 will not start to move rearwardly until a later period in the compression stroke of the member E. When said guide rods are backed ofi' or screwed further out oi' the jaw 20, the tension oir' the springs will be reduced, and accordingly, the jaw 20 will start to move rearwardly at an earlier period in the compression stroke oi" the member l. When it is desired to handle relatively wide strips in thel machine, the stops 201L which limit the rearward movement ci the 2() are backed olf or turned in such a direction that the heads on said stops are positioned farther away from the guideway member This permits the aw 20 to move rearwardly farther, and consequently, makes it possible to compress wide and narrow strips approximatelyi the same degree. rlhe locking mea-ns which holds the liaw 20 in rearward position may consist of pivotally mounted locking devices 36 on the side members B of the traine of the machine which are provided at their Viront ends with hooks or notches' that (io-operato with literal projections 37 on the ends ot the 20. lWhen the jaw 20 is in its normal position, shown in Figure 6. the lateral projacctions 37 at the ends ot same are so arranged that they are just out of engagement v. notches in the front ends of the locking devices 36. and when said tlaw moves rearwardly into the position shown in Figure 8, the locking devices 236 move upwardly under the influence of springs 3S, thus causing the projections 37 vto be positioned in the notches in said locking devices7 and'consequently, holding` the jaw 2O in its rearward position.

After the strip has been compressed-between the parts i9 and 20 it is maintained in its compressed condition for an instant or two more, so as to cause the plaits of the strip to be set, and in order that this may be accomplished without reducing the speed of the machine, means is provided for enfing the compressed strip and holding i its com aressed condition while the oscillating member E of the compressing mechanism is moving upwardly to carry the projection 19 thereon away from the jaw 20. ln. the machine herein illustrated a setting member consisting of a plate 39 is arranged transversely of the machine at the lower end of t ie guideway member 28 between said member and the jaw 20 for co-operating with said jaw to hold the strip. in its compressed condition during the return stroke of the member li, said plate 39 being carried by a transversely-disposed bar 40 which is mounted in the guideway member 28 in such a manner that it can move upwardly and downwardly. The bar 40 is carried by a plurality of guide pins 41 in the member 28 whose lowe" ends are acted upon .by coiled expansion springs 42 which normally exert pressure on said pins in a direction to move the bar 4() upwardly. Means is provided for normally locking the bar 40 .in its depressed position so 'as to hold the upper edge of the plate and the upper ends ofthe pins 41 flush with or below the concaved surface on the guideway member 28 over which the plaited strip ai is moved when the oscillating member moves downwardly, and while said means can be formed in various ways without departing from the spirit of my invention, l prefer to equip the machine with a locking mechanism composed of pivotally mounted latches 43 arranged at the opposite ends of the guideway member 28 and combined with springs 44, herein shown as lea-f springs, that move the upper or free ends of the latches 43 forwardly so as to hold shoulders or projections 43a on said latches in engagement with the end portions of the bar 40 which carries the plate 39. During the downward movement of the oscillating meinbcilil. tripping devices 45 on said member E that are arranged at the ends of same engage projections 46 on 'the extreme upper ends of the latches 43 and swing said latches rearwardly sufficiently to disengage the shoulders thereon from the bar 40 (see Figure 10). rlhe settingl member or plate 39 will now be released, but said plate will not move upwardly, due to the fact that the pla e 39 is then positioned directly underneath the projection 19 which is clamping the compressed strip against the aw 20, the side friction which the projection 19 exerts on the compressed strip `being suflicient to overcome the force of the springs 42, notwithstanding the fact that the springs 42 are strongerthan the springs 19tL whichihold the part 19 projected beyond the conveXed surface of the member E. The instant the oscillating member E starts to move forwardly, thus relieving the side friction of lthe projection 19 on the compressed strip,

the springs "42 expand and move the pins 41 andthe plate 39 upwardly, the projection 19 receding or moving inwardly into the channel in thc member ll, due to the fact that the springs 42 are stronger vthan the springs 19n which back up the projection 19. The-result isthat the setting member 39 will move into larallel relation with the jaw 20 and will co-operate with same to hold the strip compressed, as soon as the projection 19 on the member E starts to move away from the jaw 20. As the member Eapproaches its elevated position lingers 47 that project from the lower edge of said member strike against the upper ends of the .pins 41 which then protrude from the concaved surface of the guideway vmember 2S and movev said pins downwardly, thus causing the plate 39 to Abe depressed and locked automatically in its depressed position when the bar 40 moves downwardly sufliciently to permit the latches 453 to swing forwardly into engagement with the end portions of said bar.

Before the compressed strip is released from the jaw20 and the settingmember 39 by the depression of said setting member, an ejecting mechanism operates to discharge the compressed strip into a discharge chute 4S (see `Figure 4). Said ejecting mechanism preferably consists of a horizontally disposed, rotatable shaft 49 provided with ejecting rfingers 50 that travel upwardly through slots or cut out portions 51 in the upper edge portion of the jaw 20, one of said slots or cut out portions 51 being shown in Figure 6. The shaft 49 of the ejecting mechanism rotates continuously when the machine is in operation and is preferably driven by a gear 54 on one end of said shaft that meshes with a pinion 53 on the drive shaft 3, as shown in Figure 1 of the drawings. The constantly rotating shaft 49 of the ejecting mechanism also performs another function. namely, it trips the latches 3G which hold the aw 20 in its rearward position, the auto matic release of said jaw 2O being effected by tripping devices 52 on the ejecting shaft 49 which engage the latches 36 and depress said latches into the position shown in Figure G after the compressed strip has been discharged from the jaw 2O and tle setting member 39 by the ejecting devices 50. Y

The operation of my improved machine is as follows: rlhe Strip m that is to be plaited and compressed is arranged transversely of the table (l of the machine, as shown in Figure 5, and is thereafter moved rearwardly towards the plaiting rolls by the projections 15 on the sprocket chains 141:. As soon as the strip has been engaged by the rolls l and 2 the rotary movement of said rolls feeds the strip rearwardly and causes` longitudinallydisposed plaits or flutes tobe formed in the strip, thus producing a plaited strip as shown in Figure 6. The oscillating member E then moves downwardly from the position shown in Figure 6, and when the feeding devices 29 on the member E engage the plaited strip they cause said strip to be fed downwardly over the stationary guideway member Q8 into engagement with the jaw 20. rlust before the feeding devices 29 reach the jaw 2O said feeding devices are retracted or withdrawn from the converted surface of the member E by the engagement of the ends 31l of the rock arms 31 with the stationary cam plates 33 on the side members of the frame of the machine. When the projection 19 on the member E engages the `front edge of the plaited strip said projection 19 cooperates with the jaw 2O to press the plaits or folds of the strip tightly together, the jaw 20 yielding slightly during the last portion of the compression stroke of the member E, due to the force which is exerted on said jaw by the member E and said jaw becoming locked automatically when it reaches its rearward position, as shown in Figure 8. During the compression stroke of the oscillating member E the tripping devices 45 on said. member engage the latches 43 and move said latches rearwardly into the position shown in Figure 10, thus causing the transversely-disposed plate or setting` member 39 to be released from the means that normally holds said plate in its depressed position. As soon as the oscillating member E starts to move forwardly on its return sia'ol-e.` the plate 39 moves upwardly into parallel relation with the jaw 20, so as to co-operate with same to hold the compressed strip in its compressed condition while the member E continues on its return stroke. After the compressed strip has been ejected into the discl'iargc chute t3 by the lingers 50 on the rotating shaft 4:9 of the ejecting mechanism, the 4T on the member E engage and depress the pins 41 connected to the bar 40 which carries the vsettingr member 39, and when the' projections 52 on the ej ecting shaft engage and depress the locking devices 36, the aw 2() moves forwardly back to its normal position under the influence of the sprii'lgs combined with the guide rods 34 that pass through the jaw 20.

A machine of the construction above described is compact, it can be manufactured at a low cost,` it can be operated at a high speed and as it heats the strip during the plaiting operation and immediately thereafter compresses the strip and holds 1t under compression for a considerable period, the

plaits of the strip will remain folded or pressed together for a long time after the strip is removed from the machine.
